PU LLEY.

SPECIFICATION forming part ofLetters Patent No. 312,682, dated February24, 1885.

Application filed December 15. 1884. (No model.)

others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in pulleys, and has for its objectthe provision of means whereby a pulley can be readily and quicklyconnected to. or suspended from a wall, ceiling, or other place, andwhich shall be simple and durable in construction, effi cient inoperation, and cheapof manufacture; and to these ends the inventionconsists of a sheave of ordinary or preferred construction, having twocheek-plates pivoted to its axis, and adapted to embrace a portion ofthe outer surface thereof, said plates being each provided with a hookor curved extension, substantially as hereinafter more fully set forth,and particularly pointedout in the claims.

In the drawings, Figures 1 and 2 are side elevations of a pulleyembodying my improvements, showing the cheek-plates in closed and openedpositions, respectively; and Figs. 3 and 4 are an end and bottom Viewthereof, respectively, in a closed position.

Referring to the drawings, in which like letters of reference indicatelike parts in all the figures, A; designates a sheave having a groove,a, of any ordinary or pref rred construction, and B B designatecheek-plates, preferably made quadrantshaped or approximately sothat isto say, having a broad outer surface, and thence converging or taperinginward to a point where they are pivoted, as by a headed cross-bolt, b,and nut b, which passes through said plates and sheave, as clearlyshown. The said cheek-plates are of a length to extend sufficientlybeyond the edge of the sheave to permit the rope or chain to pass freelyover the sheave without contact with the plates, which are preferablycurved at their outer ends. Each of the plates is pro-, vided withflanges or rims c, which extend in Wardly toward each other, and are ofa width equal to one-half of, the width of the sheave, said plates beingfurther provided with hooks 5 5 d, preferably made integral therewith.The said hooks (Z are also preferably made with their inner abuttingsurfaces beveled, as shown in Fig. 4, the extreme ends of the said hookswhen closed extending considerably beyond the center of the sheave,thereby providing a secure and strong means for connecting or suspendingthe pulley from a wall, ceiling, or other place.

It will be observed that in order to attach thepulley tothe desired objectit is only necessary to separate the plates as shown in Fig.

3, and cause the hooks thereof to take into an aperture, hook, or othersupport provided for that purpose, and that when the plates are closedthe arms thereof will bind or be held together by the friction of theirmeeting and tapering surfaces. It will also be observed that the hooks dd are arranged in a plane parallel with their movement when they areopened or closed, thus enabling them to be quickly and readily attachedto and detached from their supporting means.

By the use of the quadrant-shaped plates I am enabled, to produce apulley which combines the necessary strength, together with lightness,and also effecta saving in metal.

The invention is particularly adapted for use in connection with a horsehay-fork, application for which I have filed of even date herewith,Serial No. 150, 660 but it will be seen that the device is capable ofapplication in other relations with equal advantages.

Modifications in the form and proportion of parts can be made withoutdeparting from 0 the principle or sacrificing the advantages of myinvention, the essential features of which will be readily understoodfrom the foregoing description.

Having thus fully described my invention, 5 what I claim and desire tosecure by Letters Patent of the United States, is-

1'. In a pulley, the combination of a sheave, and two cheek-platespivoted to the axis of the pulley, and provided with flanges and hooksrco cast integral therewith, the hooks being arranged in the plane oftheir movement when opened and closed, substantially as described. 2. Asa new article of manufacture,a pulley consisting of the followingelements in combination, to wit: a sheave, two cheek-plates havingflanges c c and hooks d d cast in one piece XVitnesses: therewith, thehooks d being arranged in the W. B. K. FITZMILLER, plane of theirmovement and made tapering J. J. FULLER.

on their meeting adjacent surfaces, and a piv- IO otal bolt orpin, asset forth.

In testimony whereof I affix my signature in presence of two witnesses.
